Answer:
a = 7
Step-by-step explanation:
3(1 - 2a) = -3a - 18
3 - 6a = - 3a - 18
Add 18 to each side:
3 + 18 - 6a = - 3a - 18 + 18
21 - 6a = - 3a
Add 6a to each side:
21 - 6a + 6a = - 3a + 6a
21 = 3a
3a = 21
Divide each side by 3:
3a ÷ 3 = 21 ÷ 3
a = 7
Answer:
8+ 4x +9y
Step-by-step explanation:
-2 + 5x + 8y + 10 - 1x + 1y
After taking out the ones in parentheses (they were taken as they were not similar to their variable). You must solve the likeness.
8 + 4x + 9y
Answer:
12 x^4 y^2
Step-by-step explanation:
6x^2y^2 and 12 x^4 y
First find the least common multiple of the coefficients
6 and 12
12 is the smallest number that they both go into
Then find the least common multiple of the x terms
x^2 and x^4
x^4 is the smallest that they both go into
Then find the least common multiple of the y terms
y^2 and y
y^2 is the smallest that they both go into
The least common multiple is
12 x^4 y^2
The answer is y=2x+5 I think
